Lisle A/C and Fuel Line Disconnect Tool Set, 8-Piece Master Kit — Compact Blow-Mold Case, OEM-Style Fit

This compact kit gathers the most commonly used disconnect tools for automotive air conditioning and fuel line service into a blow-molded case that keeps each tool accessible and protected. The set covers a wide range of OEM-style quick-disconnect fittings so technicians and DIY mechanics can remove lines without damaging plastic collars or metal fittings. Each tool is crafted for hand-powered operation, making it suitable for tight bays and mobile service work where pneumatic tools aren’t available.

Which fittings and systems does this tool set work with?

The kit targets the frequently encountered quick-disconnect fittings used on A/C refrigerant and fuel delivery lines across many domestic and import models. It includes multiple sizes and shapes to match round, flat, and multi-lobed collar designs so you rarely need to improvise.

• Eight disconnect tools sized for common automotive A/C and fuel line fittings
• Designed for OEM-style plastic and metal release collars
• Covers a broad range of domestic and import vehicle connectors

How does the storage case improve workflow?

The blow-molded case holds each tool in a dedicated slot so you can identify the correct tool at a glance and return it after use. The molded layout reduces rattling and tool loss in a busy shop or service vehicle, and the compact profile fits standard tool cabinets or under-seat storage.

• Custom-molded slots for each of the eight tools
• Secure latching and compact footprint for easy transport
• Organized layout speeds selection and reduces downtime

Can I replace individual tools from the set?

Yes — each disconnect tool in the Lisle 39900 set is available individually, allowing you to replace a worn size or add a specialty tool without buying a full kit. This modular approach keeps long-term costs down and lets you tailor your collection to the vehicles you service most often.

• Individual tools sold separately for selective replacement
• Easy to expand your toolkit without the full kit purchase
• Affordable spare parts reduce downtime and inventory overhead

What makes these tools reliable for hand-powered use?

Each disconnect tool is shaped for positive engagement with the fitting collar and built to withstand repeated hand leverage without deforming. The simple hand-powered design eliminates the need for air lines or electric drive tools when working in cramped or mobile environments.

• Durable construction suited for repeated manual use
• Ergonomic profiles for secure gripping and control
• Ideal for confined spaces where power tools are impractical

Who is this for: The Lisle 39900 Master Disconnect Tool Set is aimed at professional technicians, mobile mechanics, and well-equipped DIYers who regularly service automotive A/C and fuel connections. It’s particularly useful when you need a reliable, portable selection of disconnect sizes in an organized case — a practical addition to a service truck, garage bench, or home workshop.
